Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610666, here are decompositions:

7 + 8610659 = 8610666
17 + 8610649 = 8610666
23 + 8610643 = 8610666
59 + 8610607 = 8610666
67 + 8610599 = 8610666
83 + 8610583 = 8610666
107 + 8610559 = 8610666
109 + 8610557 = 8610666

Showing the first eight; more decompositions exist.
